Presented at GeeCON (18th May 2012) Video available on Vimeo: https://vimeo.com/44792649 In most disciplines built on skill and knowledge, from art to architecture, from creative writing to structural engineering, there is a strong emphasis on studying existing work. Exemplary pieces from past and present are examined and discussed in order to provoke thinking and learn techniques for the present and the future. Although programming is a discipline with a very large canon of existing work to draw from, the only code most programmers read is the code they maintain. They rarely look outside the code directly affecting their work. This talk examines some examples of code that are interesting because of historical significance, profound concepts, impressive technique, exemplary style or just sheer geekiness.

1. Cool Code
@KevlinHenney

4. There is an art, craft, and science to
programming that extends far beyond
the program. The act of programming
marries the discrete world of computers
with the fluid world of human affairs.
Programmers mediate between the
negotiated and uncertain truths of
business and the crisp, uncompromising
domain of bits and bytes and higher
constructed types.

36. There have always been fairly severe
size constraints on the Unix operating
system and its software. Given the
partially antagonistic desires for
reasonable efficiency and expressive
power, the size constraint has
encouraged not only economy but a
certain elegance of design.
Dennis Ritchie and Ken Thompson
